Okay, so I noticed a while ago that my rear would sag a bit over night.. and I could hear a slight leak when I would shut the car off from the rear, figured it was the rear distribution block that was leaking a little, no big deal.

Well, before I could get around to repairing that, the rear is now slammed and will not raise at all. (before, it would raise up and just leak out after a day or two of the car not running, and not completely out either)

The compressor kicks on but no parts of the car will raise.

I have a code saying the pressure system leaks.

When I test the pump, the release valve works fine, but the compressor (which is about 1.5 years old) will get up to 6-7 bar fine and quickly, then stay there instead of getting up to 14..


Any ideas on this?

I had enough with mine and just installed the coil over kit from BC. Best thing I have done...no more worry. Not sure what your problem is but I do have rear bags if you need them for sale.

I'm assuming it's not the bags at the moment since the compressor won't build up pressure. I think if there was a leak in the bags it would still build up pressure before releasing it to the bags.

So I'm hoping the bags are okay, but if not I will get in contact with you.

have you tested the valve block. If its not closing the valves at the right times, the compressor just won't build anymore pressure.

Could also be that you've had leaks for a while and simply worn out the compressor.

new compressor is only about $260 so not the end of the world.

I have a valve block for sale if needed

My valve block works fine, think it's either a reservoir or the rear distributor... Car is too low to get under it in my driveway though

Does anyone know if air is supposed to come out of the tube on the compressor while the compressor is pumping?

cwmateiuc

I can't figure it out, I can lower the car via SDS, so I'm assuming the valve block works. I can't raise the car, it says I have a leak somewhere.. I cant find any major leaks, so I'm assuming the pump itself could be leaking?

OK Do this. I am no expert but here goes. You have THREE air tanks in the back of the car. Two are routed directly to the bags , within 12 inches of each bag and they are aluminum tanks , easy to find right near tail pipes. The other storage tank is on the passenger side, rear trunk, behind the carpet/insulation. This is a pretty big aluminum tank with one line going to it and from the distribution block.If these are not pressurized at all times , the suspension will not have enough "boost" to raise the rear up. SO..... if there is a leak this could/will be your problem. Try and loosen the line and it should start hissing. This has proven to be a difficult leak finder because being isolated in the trunk you never hear it leaking.

Hi

I will be keeping a close watch on this thread...

Same problem on my car!

I sprayed the rear tank with soapy water, no leaks.

I have also checked the tanks underneath the car, no leaks.. But I'm pretty sure they're not
Getting air to begin with at the moment.

I think the air is leaking from the pump pressure release valve. Is air supposed to be coming out of the tube on the pump as it is pumping?

SICAMG

Yes it should be coming out of the pressure tube but remember it is going to the main distribution valve as well and may not be geting past that. When stars is hooked up can you run the pump and get under the car to see and here whats going on?

cwmateiuc

Yeah I have the front bumper off. I sprayed the area with soapy water and no leaks whatsoever... I'm thinking it could be the valve block itself..

But wouldn't the pump still reach the pressure it should reach?

cwmateiuc

Still trying to figure it out. Car is still on the ground. Compressor works but car will not raise.
